As graphics cards become more and more powerful, cooling them becomes a
daunting challenge. In a typical ATX tower system, the graphics porocessing
unit (GPU) is in the middle of the case, upside down, with its own printed
circuit board (PCB) obstructing a lot of the heat being put off. To complicate
matters, GPUs can now easily pull more than 100W and with PCB lengths increasing,
sometimes the system airflow can be effectively cut off.

The Duorb by Thermaltake is one of many GPU coolers available to PC enthusiasts
who want better than stock cooling. It is a dual fan cooler like the Xigmatek
Battle-Axe, but is only equipped with two heatpipes. Its basic design
is similar to the Zalman
VF900-CU, which was a star in its day. The VF900 is simply too small
to effectively cool most current GPUs. A larger radial cooler with a massive
fan would seem like an obvious evolutionary step, but you can only make it
so big before it touches the expansion slots on the motherboard. Thus, Thermaltake
has decided to go horizontal, splitting what would have a been a small, radial
copper cooler into two small semi-radial coolers. The result is the Duorb,
or two orbs as the name suggests.

Box and interior packaging are fairly compact by Thermaltake's standards.
